Fish cut into portions, season with salt and pepper, folded into a container. Prepare marinade: mayonnaise whisk with the orange juice, pour over fish, mix gently and leave for an hour to marinate. Spread on foil and bake in preheated oven 180 C for 15 minutes. No need to add any seasoning to the fish, no greens, no cheese, then very interesting taste gives the fish an orange. Bon appetit!
